' CONCRETE-FORM.

Specification of Letters Patent.

Patented Apr. 1, 1919.

Application filed June 12, 1915. Serial No. 33,799.

To all whom it may concern:

Be it known that I, STEWART R. MOKAY, a citizen of the United States,residing at East Cleveland, in the county of Cuyahoga and State of Ohio,have invented a certain new and useful Improvement in Concrete-Forms,(Case B,) of which the following is a full,

clear, and exact description.

This invention relates to forms intended for use in buildingconstruction of the monolithic concrete type, wherein. the formsgenerally comprise vertical posts with intermediate panels which withthe posts provide a surface against which soft concrete may be laid.

Theinvention to which this application relates resides in a unit form ofa construction which will enable successive units, com- "prisingvertical posts and intermediate panels, to be conveniently assembled andplaced in operative relation to each other with accuracy,

Generally speaking, the invention comprises the elements andcombinations thereof Fig. 1; Fig. 3 is a transverse section of a formshowing one method of holdingplates in position Fig. 4 is a fragmentarysectional view showing another form or method of holding the plates inplace, the sectional view corresponding to the line 4-4 F1g 1;

Fig. 5 is a. perspective showing the manner in which two unit forms maybeunited. Fig. 6 shows the same parts as shown 1n Fig. 5 but inseparated condition; and Fig.

7 is a partly sectional view on the line 7-'7 of Fig. 1. I

In general it may be explained that my invention relates to a form whichis to be erected in proper position with respect to the foundations of abuilding for the purpose of forming the superstructure of monolithicconcrete.

t In the construction herein proposed the form may be dismantled byremoving its component parts and the same form may be again utilized andrepeatedly utilized so long as the material itself will last.

My construction embodies vertical posts which are spaced apart andreceive a series of panels between them which when' assembled form asurface against which soft eons crete may be laid. v The distance whichthese posts may be spaced apart is not material to this invention, thedistance being chosen to provide what maybe a convenient space so thatthe panels are not so large as to be unwieldy to handle. The number ofelements,

that is to say, the number of posts in series,

will depend entirely upon the length of the wall construction which isto be erected. In the present instance I have shown two, which willserve to illustrate the manner of their erection and the manner of theircooperat1on with the panels;

As I have shown it. each unit comprises two vertical posts includingeach what I may.

term side members 35 and 36. As shown, these side members are angleirons. To the top and bottom of these side members 35 and 36 transversemembers 37 and 38 are secured.

. Preferably these members 37 and 38 are angle irons or channel members,one flange of the member 38-lying against and extending along theforward angular portions of the members 35 and 36. These membersare-riveted to each other, so that there is formed a rectangularsubstantially rigid structure. Each unit is formed the same and therearwardly extendingflang'es 35 and 36 of each side member 35 and 36 areprovided with openings, which openings will be in alinement whensucceeding sections are brought into alinement. The sections may then besecured together by means of bolts and nuts,

as indicated at 39. or another convenient form of fastening device whichI will presently describe.

The webs or flanges 36 and 35 may be provided with pivoted retainingmember such as shown at 4:0, and more plainly shown in Fig. 4.

' The panels 41, which may cooperate with the unit construction thusdescribed. may be variously formed, but when the side members 35 and 36ofthe-unit are formed of angle irons, as heretofore described, thepanels 41 will be formed at each end with an extending tongue l2,whichwill be adapted to lie against the inner surface of the front 42 atboth ends of the plate, and so will press the panel 2 firmly against theside members of the unit. The manner of cooperation between theretaining member and side member of thennit will be clearlyunderstoodsun , the interior flanges of the units 35 and 36 will lieflush, so as to form a plain surface against which concrete may bedeposited.

It will be desirable to place the l'l'lGllil'iQlS 43 and attach them tothe inner facing of the 'flanges of the side members 35 and 36, to'bring the surface of these inner flanges to lie flush with the innerfaces of the panels 42.

It will be seen that the several members 35, 36, 37 and 38 arepermanently secured together,- forming a frame which I have termed aunit. These various frames will be assembled with respect to each otherin proper manner to form the wall or surface which is to be molded ofconcrete.

In Fig. 3 I have shown a modified form of construction by which thepanels 41 may be held with respect to the frame or unit; and, also, Ihave shown another modified form of frame. In this construct-ion theside pieces are formed with an individually extendlllg outer flange 45.

This outer flange is adapted to receive an angular shaped retainingmember 46, the retaining member engaging the flange 45 and alsoengagingthe e X- tension 42. The member 46 is chosen to be of such sizethat it will fit tightly and so press the panels 41 firmly against theto nuts and bolts are difficult to keep together when not in use. and Ihave, therefore. devised a means which retains all the parts of theclamping means together.

At 47 and at 48 are indicated two of the rearwardly extending flanges ofadjacent unit sections. In the member 48 there is formed a slot 49having an enlarged head part 50. In the member 47 there is an opening inthe form of an elongated slot 51. Through this slot there extends amember 52 which has a head portion 53. The head portion prevents themember 52 from passing throughthe slot 51, and at one end of the member52 there isa head 54 which also prevents the member 52 from passingthrough the slot. This member 52 may be formed in any desired manner,but preferably it is formed of two pieces of material riveted togetherwith the inner ends turned up to form the head 53. j

The member 52 is formed with the slot 55' which is adapted to receive awedge 56. This wedge is provided. with heads or pro-- j ections 57 ateach end thereof, so that it can not move out of the slot 55. Theopening 51 is of greater diameter than the head53, so that the head 53may be slipped through the opening 50 when the members 47 and 48 arebrought together. The wedge will then be moved into the slotted portion48 and the wedge driven into the slot 55. This will hold the members 47and 48 tightly together.

It will be seen that when the members 47 and 48 are disengagedthe member52 and the wedge are carried by the member 47 and cannot beremoved'therefrom'unless the member 52 is willfully mutilated for thepurpose of removing it.

There will, of course, be asuffi'ci'ent number of these retainingmembers carried by each unit or frame, so that the adj acentunits may besecurely fastened together.

Having described myinvention, I'claim i. In a formof the characterdescribed, a unit comprising side membershaving flanged portions and endmembers to which the side members are secured, one of'said side membersin the flanged portion thereof being provided with a slot, aretainingmember extending through said slot, said retaining member being providedwith a head, said retaining member also having a slot and a wedge insaid slot, means-for retaining the wedge in said slot, the flangedportion'upon the other side of the side portion of said unit beingprovided with openings which are adapted to receive the head of aretaining member and a slot extending from said opening into whichtheretaining member may slide when the successive units areassembled,p'anel members extending. between the side members and means forsecuring the panel members independently to the side members.

2. In a form ofthe character described, a plurality of units, each ofsaid units comprising side members and end members to which the sidemembers are permanently secured, means for securingthe side members ofadjacent units together, and panels extending between the side membersof each unit, and means for holding said panels in position with respectto the side of the unit.

3. In a form of the character described, the combination with aplurality of units, each of said'units comprisingside members and endmembers which are permanently secured together, the side members havingflanged portions, means engaging the side portions of adjacent units tohold the units together, panels extending between the side members ofeach unit, andmeans cotiperating with'the side members and thepanels forholding said panels in position with respect to the side members of theunits.

4. In a form of the character described, a plurality of units each ofsaid units compris ing sideinembers'and end members to which lee theside members are permanently secured, means for securing the sidemembers of adjacent units together, the side members of each unit havinginwardly extending flanges, panels which cooperate with the saidflanges, and means for holding said panels in engagement with theflanges of the side memers.

5. In a form of the character described, a plurality of units each ofsaid units comprising side members and end members to which the sidemembers are permanently secured, means for securing the side members ofadjacent units together, the side members of each unit having inwardlyextending flanges, panels having tongues at their ends the said tongueportions cooperating with the flanges of the side members, and means forholding each panel independently in engagement with the flanges of theside members.

In testimony whereof I hereunto aflix my signature in the presence oftwo witnesses.
